HERMAN ETAL SNAP ATTACHMENT FOR POLISH CANS AND THE LIKE 2 Sheets-Sheet 2 Filed Feb. 19, 1960 ,Afmsmsy United States Patent 9 3,008,164 SNAP ATTACHIVIFJNT FOR POLISH CANS 2 Claims. (Cl. 15-160) This invention concerns a snap-on polisher or applicator attachment for cans containing fluid cleansers, detergents, polishes, and the like.

According to the invention there is provided a base having a curved wall adapted to be fitted into abutment with a. cylindrical wall of a can containing a fluid cleanser or polish preferably under pressure for dispensing via a spray nozzle. The base is provided with one or more pairs of spring fingers adapted to embrace the can so that the base is securely but removably held thereon. Mounted on the base is a brush, polishing cloth, bufiing pad, sponge or other suitable polisher, buifer or applicator for the fluid dispensed from the can.

It is therefore a first object of the invention to provide a snap-on attachment brush or buffer for a cylindrical can of cleaning or polishing fluid.

It is another object to provide a snap-on attachment of the character described provided with a curved base having one or more arcuate slots or grooves in which are flush-fitted bands having projecting portions defining spring fingers for embracing the can upon which the attachment will be mounted, and a polishing member secured to the band.

A further object is to provide a snap-on attachment having a slotted base in which one or more spring bands are removably mounted for replacement by larger or smaller bands depending on the size of a can to receive the attachment, there being a polishing member secured to the base.

A still further object is to provide a snap-on attachment for a can, the attachment including a base carrying a polishing member, the base having a curved, arouately slotted wall, with a pair of spring fingers adjustably disposable in the slot for engaging the attachment on cans of different sizes.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various rfiovgl features of the invention are more particularly set In the accompanying drawings forming a material part of this disclosure:

Referring to FIGS. 1, 2 and 3, there is shown a snapon attachment 20 including a rectangular plastic block 22 serving as a base for the attachment. The block 22 has a curved rear wall 24 formed with a groove or slot 26 extending transversely across the block. Within the groove and flush with wall 24 is a plastic, springy band 28 secured by a suitable cement layer 30. Curved spring fingers 32 extend outwardly from the block and curve around so as to embrace more than one half of the circumference of the cylindrical wall 34 of a cylindrical aerosol can 35. The groove and band are centrally located in the block and the spring fingers hold the curved wall 24 of the block in abutment with the cylindrical wall of the can. The length of the block is equal to the distance between the upper and lower annular beads 3-6, 38 of the can so that the block is prevented from movement in an axial direction on the can by the engagement of its top and bottom edges 40, 42 with the beads 36, 38. Secured to the front wall 25 of the base block by a layer of cement 27 is a. resilient foam plastic pad 29. The can has a finger operated valve 31 which may be protected by a removable cap 33 shown by dotted lines.

It will be readily apparent that the attachment 20 is readily snapped on and off the can by engagement and disengagement of the spring fingers with respect to the cylindrical wall of the can. The valve 31 will be pressed in the usual manner to dispense a cleansing or polishing fluid from the can upon a surface to be cleaned or polished. The can body can then be used as a handle to rub the pad 29 over the surface on which a spray of the cleaning fluid has been deposited, to clean buff and polish the surface.

In FIGS. 4-7 is shown another snap-on attachment 20 in which block 22. has two spaced, parallel grooves 26 and 26 located near the top and bottom edges 40*, 42 of the block in wall 24*. The bottom edges 45 of the grooves are slanted upwardly to V-grooves in which can be engaged mating beveled portions 23 of spring bands 28, 28 The upper edges 46 of the grooves are disposed at the upper edges 49 of the spring bands. Depending spaced projections 48 are formed on the upper edges 46 to seat in recesses 50 in the upper edges 49. Arcuate spring fingers 32 are provided by the outwardly extending end portions of the bands. The central portions of the bands fit into the grooves and are securely but removably held thereby. The provision of two bands with four cooperating spring fingers insures a more secure engagement of the attachment on wall 34 of the aerosol can 35. The length of block 22 equals the distance between the upper and lower beads =36, 38 of the can. Secured to the front wall 25 of the block 22 by a layer of cement 27 is a brush 52 provided with forwardly extending bristles 54.

The attachment 2 2 is thus provided with a brush which can be snugly but removably mounted on a can for brushing a surface upon which a fluid spray dispensed via valve 31, has been deposited.

In FIGS. 8-10, block 22* of attachment 20 has wall 2.4 provided with two grooves 26 and 26 in each of which are removably disposed two spring fingers 60, 62. Each spring finger is provided with a plurality of recesses 50*- in top edge 4 9 adapted to receive projections or tits 48 formed on the undersides of upper edges 46 of the grooves. The bottom edges 45 of the grooves are slanted to receive beveled portions 23 at the bottom edges of the spring fingers. The spring fingers can be adjustably inserted in the grooves to a greater or lesser extent to provide longer or shorter external finger projections This permits the attachment 20 to be mounted on cans of smaller or larger diameter. The block 22 carries 2 9 a pad 29* held by cement 27 but it may if desired carry a of said bands being formed with mating V-grooves and brush such as shown at 52in FIG. 6. beveled portions to removably retain the bands in the If desired, more than two grooves and spring bands grooves. or pairs of spring fingers may be employed for still 2.
